- A wide range of sizes: from 1 inch to 76 inches
- Both standard and custom designs
Total Flux Measurements
- External and internal lamp mounting geometries
- Fully optimized designs
- Auxiliary lamps included for highest accuracies
- A wide range of sizes: from 4 inches to 76 inches
- Washable coating on larger spheres
- Standard and custom designs
Diffuse Reflectance/ Transmittance Measurements
- A wide range of accessories available
